Towing With Air Suspension — If Equipped
1. Verify that the vehicle is at the normal ride
heig
ht.
NOTE:
The vehicle must remain in the engine run position
with
all doors closed while attaching a trailer for
proper leveling of the air suspension system.
2. Position the truck to be ready to connect to the
tra
iler (do not connect the trailer).
3. Enable tire jack mode through the instrument
clu
ster or touchscreen radio settings. Tire jack
mode will be canceled and the procedure must
be restarted if the vehicle is driven at speeds
above 5mph (8
km/h).
4. Measure the height from the top of the front
whe
el opening on the fender to ground; this is
height H1.

5. Attach the trailer to the vehicle without the

ght-distributing bars connected.
6. Measure the height from the top of the front
whe
el opening on the fender to the ground;
this is height H2.
7. Install and adjust the tension in the
wei
ght-distributing bars per FCA recommen-
dations so that the height of the front fender is
a
ppr
oximately (H2-H1)/3+H1 (about 1/3 the
difference between H2 and H1 above normal
ride height [H1]).
8. Use the instrument cluster or touchscreen
rad
io settings and switch off tire jack mode.
Make sure the truck returns to normal ride
height. Perform a visual inspection of the
trailer and weight-distributing hitch to confirm
the manufacturer’s recommendations have
been met.
9. The truck can now be driven.
NOTE:
For all towing conditions, we recommend towing
with
tow haul mode engaged.
